InTouch Care is an Active RFID tracking system. The system is comprised of four basic 
elements: 

1.  TAGS – The TAGs are battery operated and are comprised of an RF Transceiver 

and a few peripheral components.  The TAGs are small devices with about 1” X 
2” foot print. They are typically attached to assets or people that need to be 
tracked.  

2.  Spiders – The Spiders are also battery operated and are equipped with similar to 

the TAG RF transceiver and other peripheral components. Unlike TAGs, Spiders 
are not mobile. They are typically attached to either ceilings or walls.  Their 
function is to improve the localization capability of the system. 

3.  STARs – The STARs are operated either using an external power supply or a 

POE power supply within the device. STARs are also equipped with essentially 
identical RF section to both the TAGs and the Spiders.  The STARs are also 
equipped with a LAN chip for communication with the server. 

4.  Server – The servers can be either local or can be connected directly to any 

Internet server. The Servers are in direct communication with the STARs.
